194. Industrial policy detectives: China’s subsidies for shipbuilding

Episode Summary

Executive Summary: The episode examines China’s shipbuilding industrial policy, using a new method to infer opaque subsidies from firm behavior and costs. It finds China spent about $90 billion from 2006-2013, mostly on entry subsidies, rapidly making China the world’s largest shipbuilder—but with low profitability, fragmented firms, and little evidence of learning or spillovers. The subsidies lowered freight rates and boosted trade, while shifting market share from Japan and South Korea.

Main Topics: China’s rise in global shipbuilding (Priority: 5/5): The episode traces how China moved from a minor player in the early 2000s to global dominance in shipbuilding, overtaking its 2015 target by 2009. How ships and shipbuilding work (Priority: 3/5): The discussion explains the main ship types used in trade, how they operate, and why shipbuilding is a strategic, capital- and labor-intensive industry. Measuring opaque Chinese subsidies (Priority: 5/5): Myrto Kaloupsidi describes a novel empirical approach that infers subsidies by detecting a cost break in 2006 using global micro-level industry data and a quantitative model. Size and composition of subsidies (Priority: 5/5): The research estimates massive support, with entry subsidies dominating and production/investment support playing smaller roles. Economic effectiveness and firm outcomes (Priority: 5/5): Despite huge subsidies and output growth, the policy generated low returns, weak profitability, and a fragmented industry with many small, inefficient shipyards. International spillovers and trade effects (Priority: 4/5): The subsidies reduced ship prices and freight rates, increased Chinese trade, and displaced production from more productive Japanese and Korean shipyards. Lessons for industrial policy design (Priority: 4/5): The episode argues that industrial policy design is difficult: blanket entry subsidies are inefficient, while targeted production/investment support performs better, especially when aimed at productive firms.

Key Arguments: China’s shipbuilding subsidies were real, large, and measurable through indirect evidence, despite the absence of obvious direct-payment records. The policy’s biggest component was entry subsidies, which encouraged many marginal firms to enter and created a fragmented, low-scale industry. The industrial policy achieved China’s stated market-share goal quickly, but did not generate strong profitability or efficiency gains. There is little evidence for common justifications such as learning by doing, upstream/downstream spillovers, or strategic trade rents in this case. Subsidies increased ship supply, lowered freight rates, and boosted Chinese imports and exports, but the benefits to global welfare are ambiguous. A significant share of China’s market-share gains came from displacing production in Japan and South Korea rather than expanding total world output. Targeted subsidies and consolidation policies are more effective than blanket entry subsidies, but the actual whitelist favored state-owned or non-optimal firms. Shipbuilding is presented as a broader example of China’s industrial policy in sectors like steel, solar, and auto parts, though the approach appears to have shifted over time toward larger, higher-tech firms.

Data Points: Estimated total shipbuilding subsidies: $90 billion - China’s shipbuilding support from 2006 to 2013 Average annual subsidies: About $11 billion per year - Average annual support implied by the 2006-2013 estimate Subsidies as share of industry revenue: About 50% - Estimated subsidies relative to total Chinese industry revenue over the period Share of subsidies for entry: About 70% - Most support went to new firms entering the industry China’s shipbuilding market share before policy surge: About 10% - China’s global share in the early 2000s Global market concentration before China’s expansion: More than 80% controlled by Japan and South Korea - Japan and South Korea dominated shipbuilding in the early 2000s New Chinese shipyards per year after 2006: 30 to 40 per year - Entry wave following subsidy implementation New shipyards per year in Japan/Korea: Barely 1 per year - Comparison with China’s entry boom China became the largest shipbuilding producer: 2009 - China beat its 2015 target six years early Original target year for largest producer status: 2015 - Goal announced in China’s policy plans Freight-rate decline: About 6% - Estimated effect of subsidies on shipping costs Chinese trade increase: About 5% - Trade expansion associated with lower freight rates Annual trade impact: About $150 billion - Value of increased Chinese trade attributed to freight-rate decline Share of China’s market-share gain stolen from Japan and South Korea: About 70% - Portion of China’s rise that came from displacement rather than net new production

Pivotal Quotes: "China hopes to become the world's largest shipbuilding country in terms of output by 2015." — Premier Zhu: 2002 inspection of the China State Shipbuilding Corporation, signaling China’s industrial ambition "The idea being they want to now create conglomerates that are going to compete globally and become world leaders in production." — Myrto Kaloupsidi: Explaining the later whitelist/consolidation phase after the financial crisis "Design is hard." — Myrto Kaloupsidi: Her takeaway on the difficulty of selecting the right industrial-policy instruments and targets

Implications: The episode suggests industrial policy can reshape global markets, but design matters enormously. For the WTO and policymakers, the challenge is measuring hidden subsidies and distinguishing growth-enhancing targeting from wasteful entry support and market distortion.
